After a recent Ambulatory Sleep Test (suggested by my wife, who noticed my periods of 'suspended breathing' in the night) I embarked on my CPAP journey about a week ago. Currently still trying to settle on the best mask for me, having tried med and lrg pillows, and now a med nasal mask. All have had high leak rates, and my AHIs have been all over the map, varying between 1 and 15. Because of the high variability, I don't know if posting any particular Sleepyhead chart here would be useful, but tell me differently if you think better.
Sleep test summary: 'Severe' obstructive sleep apnoea, 45.6 abnormalities per hour, mainly hypops. Frequent mild O2 desats. Average O2 desats were 'mildly abnormal' at 4%. 18 mins spent below 90% sat.
Total sleep AHI 12.9, (OA 1.7, HI, 10.1, MA 1.2 CA 0). Supine AHI 17.5, RERA 32.7. Longest apnoea 34 secs.
Weirdly the results from my machine show the majority of my apnoeas are CA, whereas none were recorded during the sleep test!
My trial CPAP machine (ResMed Airsense 10) provider is a local pharmacy (Australia). I don't have a lot of faith in the depth of their knowledge. They don't yet know that (thanks to this forum) I know how to access the deeper menu settings and display detailed data. Their menthod so far has been to set the machine to auto. I haven't done any serious fiddling with the settings apart from tweaking humidity. Suggestions welcome on how to begin arriving at settings eg pressure that would work well for me.
Thanks... Jon
